I have file "vpncerificate.cer" which need for my app for successful connection. It's possible programmatically install this certificate to the system? If yes how do this?

My app have part of code where I am create VPN profile but can't establish connection because I am install file .p12, but not a .cer. How I can get certificate from CA for my VPN, describe please full process of obtaining this certificate, and how much cost this operation? I am don't find clearly answer of this question and can't understand how it will be occur.

My app create VPN profile programmatically for user but connection fail each time. I can solved this problem doing next: I am create file .mobileconfig using AppleConfigurator and create "Certificate 2 Payloads Configured" inside this file I put file .p12 and set password for this file and file .cer. When user install this profile only after this operation VPN connection would be establish. Inside app I am use file .p12 for NEVPNManager( use NEVPNProtocolIKEv2 ). How I can install file .cer programmatically inside app or need install something else? Which advice are you can give in this situation?

I am create VPN profile programmatically using NEVPNManager all looking good. When I am try connecting to VPN each time, connection fails but if I install to system, file .mobileconfig and then try connect all work good. Also I am try by hand download certificate from (developer.apple.com - > Certificates, Identifiers & Profiles) and then install is, all work good. Inside project I did put file .p12 with certificate and load it using "Bundle.main.url". It's problem appears because app can't install certificate to the iphone system or? I am need that when user install app it can use vpn immediately, without downloading .mobileconfig and then install it to system. How solved this problem ? Only way which exist it buy certificate from CA which will be inside system or I am just did something wrong? I am don't understand where mistakes and how solve this problem)

Hello Few week ago I am was began create vpn for ios. I am was try create vpn use NEVPNManager with IKEv2 protocol but I am have trouble with certificate in iOS( because need certificate from CA ). Second which I am try was be create VPN use NETunnelProvider bu I am also can't create vpn. Also I am use information from other sources, but each time I am failed. Last time I am use AlgoVPN on my server with ubuntu and programmatically create vpn profile on ios, but I can't use this auth method without certificate and it's trouble for me. How I can create vpn only with login and password authentication method without any certificate? My app give access to blocked site in my country and I am need programmatically enable and disable vpn client. Now I am want use WireGuard but I don't know can I create or not vpn client. I am don't have many experince with these complex tasks, if you know how create vpn without pain please give me advice, should I am use this way or some else. Regards, Ihor.

Hello. I am try create VPN using NEVPNManager, I am use Certificate authentication and IKEv2 protocol. When vpn was installed on iPhone and I am try connect to server, I get this error: Connection 8: received failure notification nw_flow_add_write_request [C8.1 (Ip&Port) failed channel-flow (satisfied (Path is satisfied), viable, interface: en0, ipv4, dns)] cannot accept write requests nw_write_request_report [C8] Send failed with error "Socket is not connected" Connection 5: received failure notification only FIRST time after installation, then I am nothing get from VPN. In this question https://developer.apple.com/forums/thread/84679 If you want to continue down the NEVPNManager path you will have to get a trusted CA to issue you a certificate for your VPN server answer by eskimo. I am decide create VPN use NEPacketTunnelProvider but I am don't understand completely all what should I am expected when I will be try that. How more lot of work will be there? I can create VPN with IKEv2 for users without certificate CA trusted? Or good reason will be change authentication method from certificate to login and password for IKEv2 or change protocol on IPsec and use login, pass & secret to authentication method? Regards, Ihor.
